Isn't it odd that Wario and Waluigi are basically the only major characters who aren't a part of Super Nintendo World? (Also regarding Wario's significance in general).

Like, Diddy Kong, Daisy, Rosalina, and the Koopalings are all there but no love for Mario and Luigi's arch-rivals? Wario in general used to be a conerstone of the franchise alongside Mario, Yoshi, and DK but he's been getting less and less important as time goes on I feel. He's not even on a single piece of merch over there. Could they be planning some kind of event or expansion regarding them both (since their exclusion seems a bit odd)? Would like to hear your thoughts.
